Paste-and-go-in-new-tab

I really wish i can configure the browser like the old opera behavior. There it was possible to paste-and-go in a new tab by shortcut and not overwriting the existing page (really, I don't understand the overwriting behavior - for me it makes no sense). And to open a new tab and then paste and go is double the work. Especially the new tab is the speed dial and loads not that fast it could be. The old Opera Browser does the paste-and-go-in-new-tab quite fast.
